This is coming from a pretty religious Christian.
You have to remember that the books of the bible were written by a bunch of old guys 2000+ years ago. They were very, very wise and enlightened by the lord, but the times were different. Any ridiculous statement like being gay is a sin (which was a misinterpreted verse anyway, it had something to do with tampering with the property of your neighbor) or ones that don't believe in god or haven't heard of him don't go to heaven, should not be taken seriously today. If god made us and planned for genetics to be the way we develop, why did he allow there to be a gay gene if it's supposedly a sin? because it isn't. It was considered as a sin by a person or small group of people 2000 years ago, which at the time, seemed reasonable. If a person was raised Hindu but is an extremely kind and moral person that saved and changed lives for the better multiple times in his life, he wont rot in hell simply because he follows his heart in what he believes, he'll get a VIP ticket and get permission to cut to the front of the line when entering the golden gates. Now I supposed believing in god in the form he wants to be represented in does give you an advantage i suppose, Say a catholic that prays out of his heart everyday, is an African slave owner and rapist, he won't be seeing pearly gates any time soon. I feel that everyone has an opportunity to get into whatever form of heaven their is. Just be a good person and do not act unjust for the sake of doing so. Follow a good path or morals and stick by them, help others and serve the essence of Good. You may not get into your own vision of a good afterlife, but if you follow a good moral (such as no killing "infidels" for your god for starters) and serve the element of Goodness faithfully, I guarantee that you will love the damn out of the afterlife realm you enter.
Thank you for reading. If you didn't, I don't mind. If you think I'm full of **** blasphemy, that's nice too.
inb4 TL;DR

first of all, I am not supporting nor bashing gays, I'm just going to disagree with you on something. I believe we should accept everyone no matter what their choices be, its like would you hate your kid for disobeying you or getting in trouble at school? no probably not. no sin is greater or less than another. (exclude murder for obvious social reasons.) But about the Bible part, God did not create "gay" genetics like you are proposing. People forget to realize that we are merely in a state of "less God, more self". Giving no regard for rules because we think oh liberty I can do what I want. You ever read about Sodom and Gomorrah? Hmm, makes you think about California and New York and Las Vegas doesnt it? it's open rebellion, but if us christians are going to use the bible in a sense like that, it also says to love our neighbors and "kill em with kindness". Just because we know its not normal doesnt mean we should treat others differently. P.S. I dont support it, I accept it though

I respect that. I myself am an atheist, but I still try to live my life as a kind, respectable person because that's how I want people to remember me. When religion or heaven gets brought up, I think the same way you do. Even if there is a god, if he is truly as loving or understanding as people say he is, I have nothing to fear because I try to do well of my own free will.

And frankly, if a good person deserving of heaven gets sent to hell simply because he believes in a different god or none at all, that god would not be worth worshiping anyway.

My father is an atheist and my mother is Christian, and they agreed that they wouldn't try to influence my religious or political beliefs as I grew up. They wouldn't really talk about religion or politics until I was in high school and had started to form my own beliefs. I didn't really think much about either until then. As I grew up, any questions I had about what happened around me could be reasonably explained through science and with the abundance of information as the internet became significant. There weren't any questions that didn't have some sort of answer. There were also never any miracles or anything of the sort, in fact I probably had it pretty rough by middle-class white male standards.

In the end, I was not taught the idea of a god, did not experience anything that would make me believe in one, and had no need for one. I don't see any reason for one to exist, so I don't believe one does. It's entirely possible that I could believe in some deity if I ever have a reason to.

Alright then. I'm glad you have a good moral however, and that's one of the most important things. Haven't you ever wondered how a neutrino sized dot of infinite mass, density, heat, you name it, came into existence, and let alone exploded into existence itself? not that im trying to convert you or anything, just what do you imagine was the cause for it?

I tend to see nature and the universe in terms of cycles. People sometimes limit their ideas, like some people see the universe as needing to be created. I don't think there needs to be a creation; there just is. The universe has always existed, and always will, though certainly with a different appearance.

I see no reason why there could not be a series of big bangs, and contractions into singularity. Even the smallest of objects have gravitational attractions, and even when we get far away from earth's atmosphere it has a pull, no matter how small. Just the same, we are being pulled by the sun, which itself is slowly being pulled to the center of our galaxy where there are supermassive black holes that pull in light itself. I don't see it as impossible that at some point galaxies will condense into one black hole, at which point they begin to attract each other, eventually reaching a singularity that leads to another big bang.

Naturally this is all my own conjecture and I understand that I could easily be wrong. I wouldn't mind being wrong, in fact. It would make everything more interesting.

You'll believe that men who have no means to tell you(as they are long dead) talked to God, but you won't believe someone who is actively telling you?
Instead I'm some "silly man who should feel silly?" And these men are not silly, but enlightened and wise? You've no less reason to believe me than you have to believe them.
